9.3 PC voltage supply X10
The 24 V DC voltage supply for the control cabinet PC is connected via the "X10"
connection.
All voltages internally required are generated without any electrical isolation via
a DC/DC converter. The connection is designed as spring terminal, SPC 5/3-
ST-7,62, 3-pin, grid 7.62 mm. Connect cables with the conductor cross-sections
listed in tab. "The following conductor cross-sections are permitted for the
spring terminal at X10:" on page 16 to it.

Pin Labeling Function
1 + Supply voltage 24 V
2 – 0 V supply voltage
3 U Supply voltage in front of UPS available (see chapter "UPS without
USB interface" on page 36)
Destruction of the control cabinet PC (fire haz-
ard) due to polarity reversal of the connection
at the X10 plug without additional external pro-
tection
Ensure that the polarity at the X10 plug and the dimensioning of the fuse are
correct.
Danger without safe separation!
The 24 V DC input voltage must comply with the requirements of the "safe sepa-
ration"!
Plug and remove the plug connection only if there is no voltage!
